A few new functionalities: – game ends when enemy moves beyond bottom of screen. – score increases every second. – enemy speed moves faster as score increases.
In this lesson we talk about how to find the intersection, union and complement of sets.
In this lesson we fix the bug where the enemies and your spaceship move off the screen boundary. We also make it so when enemies collide with your missiles, they reset back to the top with a random x coordinate.
In this video we introduce you to Venn Diagrams, an important concept in set theory. We also talk about how to put some real life information into a venn diagram. We will talk more about how the venn diagram relates to set theory in the next lesson.
In this lesson we design some random movements for the enemies as they come downwards at the spaceship randomly moving left and right.
In this lesson we do a quiz testing the knowledge you have learned from the last two lessons – is an element of, is a subset of, finite, infinite, cardinality etc.
In this tutorial we create some still enemy objects, and make them disappear when they collide with our missiles.
Today I explain the concepts of subset, empty set, finite set, infinite set, equal set, equivalent set, and cardinality.
In this tutorial we fix a potential future bug by limiting the array size of missileArray to 5. We create 5 missile picturebox objects at the beginning of the game and change their positions during the game, instead of adding a new picturebox element to the array (and making the array bigger and bigger) everytime …
In this lesson we learn about what a set is, and the symbol for “is an element of” and how to use that symbol.
